Exoplanets are planets that orbit stars outside our solar system. Over 4,000 exoplanets have been discovered so far, with some located in the habitable zone where conditions might be suitable for life.
Astrobiology is the study of the origin, evolution, and potential distribution of life in the universe. It combines elements of biology, chemistry, astronomy, and geology to investigate the conditions that support life beyond Earth.
NASA (National Aeronautics and Space Administration) is the United States government agency responsible for the nations civilian space program and for aeronautics and aerospace research. NASA has been involved in many missions related to the search for extraterrestrial life.
SETI is an organization dedicated to the scientific search for intelligent extraterrestrial life. SETI researchers use radio telescopes to scan the skies for signals that could indicate the presence of alien civilizations.
The habitable zone around a star is the region where conditions may be right for liquid water to exist on the surface of a planet. This zone is a key factor in determining the potential habitability of exoplanets.
Cosmic evolution is the study of the long-term changes in the universe, from the Big Bang to the formation of galaxies, stars, and planets. Understanding cosmic evolution is essential for predicting the conditions that could lead to the emergence of life.
